Method and system for monitoring trains in metro depot based on UWB

Abstract

An embodiment of the invention provides a method and system for monitoring trains in metro depots based on UWB. By means of the method, train head distance information and train tail distance information which are determined based on a UWB technology are obtained; train head position information is determined based on the train head distance information; train tail position information is determined based on the train tail distance information; and finally, based on the train head position information and the train tail position information, the occupation range of a target train on a train running track is determined, and the target train is positioned. Third-party equipment data are introduced in the entire positioning process, a train head and a train tail of the target train are accurately positioned through the two-dimensional precise ranging capability of the UWB and the triangular positioning principle, the occupation scope of the target train on the train running track can be determined, the accurate train parking position can be ensured by the metro depots, whether the target train is complete or not can be further determined, and the complete marshalling of the target train is ensured.

Description

technical field [0001] The invention relates to the technical field of rail transit, and more specifically, to a method and system for monitoring trains in subway depots based on UWB. Background technique [0002] With the improvement of living standards and the increase in the demand for train transportation, it is very important to locate the train to determine the position of the train for train scheduling and accident prevention. [0003] At present, the positioning of the train is usually realized by the interval positioning method, specifically, the beacon positioning is adopted, and the beacon is installed along the train running track to reflect the physical sign of the absolute position of the train running track. The beacon is similar to a non-contact integrated circuit (Integrated Circuit, IC) card. When the train passes the beacon, the electromagnetic wave emitted by the vehicle antenna stimulates the beacon to work, and transmits the absolute position informatio...

Problems solved by technology

However, this positioning method has a high dependence on the rail transit signal system, and cannot exist alone as a positioning method. It must rely on some data input from the rail signal to work normally.

For example, in the case of passing a turnout, the traditional speed integral plus single-point positioning mode cannot complete the positioning without the track signal system notifying the turnout closing direction
